Since the cards are rclativeiytff andunyie'ldin theyare carried by the cylinder at an ang e vtotheperipli'cry thereof and will vwipe across theend surface ofthe feedtable as they are carried beneath the same. It vis E the printed sidewhich is thus wiped and, as

the ink is of course wet, it frequently happens that switchingr landfaulty work resuits. It is the primary object of iny in- '40 `vention tolift the feed, table at the moment that the card is carried beneath thesame,

and to lower said feed table to working position immediately thereafter.y

A further object of my invention is to 4p provide a device of th'e abovecharacter which may readily be attached to printing presses of commonuse and construct-ion with the addition of practically no operatingparts., 60 .Av further object of my invention is to make the lift-of thefeed table adjustable te the minutest degree so' as to readily adapt themovement of the feed table to the size o? the cards being printed. Afui-ther oh`ect of my invention is to provide ineens forlifting andreturning the Specification of Letters Patent. Applicationfiled-September 23, 1911. Serial No. 650,966. A

.The frame of the printing press comprises longitudinal frame members 10andf11, rear .uprightsf 12, a transverse frame member 13, intermediateuprights 1 5 supporting oblique frame pieces 16 upon which rests thefeeding table 17, and central upright brackets 1S providing journals forthe feedingcylinder 19 below which reciprocates the printing bed notshown. The rear portion gf the feedv table 17 is normally stationary;Said printing table is cut across by a beveled joint 20 as shown in Fig.1, the forward poi-- tion of the table 2l being pivoted to a rod 22journaled in the upiiglits 12 and :i'haliger 23 depending from the lowerside of stationary feed table 17, this construction per initting theforward part 21 of the feed table to be swung back so that access may behad to the printing bed when same is in its rearward position. The frontedge of feed table 2l is provided with a lip 24 and with spring fingers25 which as shown in dotted lines in Fig. 1 come into close proximity tothe periphery of cylinder 19 when movable table 21 is in its lower oroperative position, said movable table then having itsA surface in thesame plane with that ofstationary table 17, said plane being aproximately tangent to the periphery of der.
